思路：

step1：对应输出打印即可；

代码如下：

guest_list = ['Niuniu','Niu Ke Le']
print('{}, do you want to come to my celebration party?'.format(guest_list[0]))
print('{}, do you want to come to my celebration party?'.format(guest_list[1]))
guest_list.insert(0,'GURR')
guest_list.insert(2,'Niumei')
guest_list.append('LOLO')
print()
print('{}, thank you for coming to my celebration party!'.format(guest_list[0]))
print('{}, thank you for coming to my celebration party!'.format(guest_list[1]))
print('{}, thank you for coming to my celebration party!'.format(guest_list[2]))
print('{}, thank you for coming to my celebration party!'.format(guest_list[3]))
print('{}, thank you for coming to my celebration party!'.format(guest_list[4]))
